Tanzania is blessed with natural advantages that few countries in the world can compete with, ranging from Africa's highest mountain to its deepest lake and the tropical "spice islands" of Zanzibar. National parks and game reserves cover one-seventh of the country, and include the vast plains of the Serengeti, (famous for its vast migratory herds of plains animals); the famed Ngorongoro volcanic crater; and the Selous National Park, the largest game reserve in Africa. All the big game is here and in parks like Ruaha their habitats are little disturbed, as mass tourism is yet to impact on Tanzania as it has in neighbouring Kenya and South Africa.
On top of this, the country is filled with friendly people who are happy to open their homes to visitors and guide them through the beauty of their towns and parks. Tanzania is also an ancient place with historical sites of global significance. At least six civilizations have left remains of their culture and history in Tanzania. In 1959 archaeologist Dr. Louis Leakey found the remains of the earliest known man in Olduvai Gorge.
